When an EV battery reaches the end of its automotive life, it typically still has about 80% of its storage capacity and can be reused in a second life as a stationary power source, potentially as grid-connected storage, reducing the need for new battery production and reducing landfill waste.
To successfully repurpose EV batteries, it must first be safe. Each battery needs to be evaluated individually because each one has been exposed to different charging and discharging conditions during its use in a vehicle. UL has worked with input from automakers, battery reclaimers, utility providers and academics to develop the safety standard UL 1974.
In this webinar, learn from UL battery experts Laurie Florence and Maurice Johnson the scope of UL 1974 and how it has become the protocol to measure the condition, safety and energy capacity of each individual battery pack before it can be integrated into a stationary energy storage system.
